BMP180 Barometric Pressure and Temperature Sensor
Introduction
The BMP180 is a simple sensor that measures barometric pressure and temperature. The chip is old, no longer manufactured, and often sold mounted on small boards that provide an I2C interface so that the BMP180 can be incorporated into hobby projects developed for Arduino, Raspberry Pi and similar platforms. Adafruit provide a C library for the BMP180 which can be used with Arduino.
The BMP180 is used in early prototypes of a sensor board with the intention of replacing it with a more modern component.
Application: software and function
The BMP180 is used as a component on the prototype sensor board. The software used to read data is contingent on the operating system used, and the standard Arduino library written by AdaFruit was used in initial prototyping.
